Wireless Sensing Lets Users “Train” Smartphones for Gesture Control

University of Washington researchers have developed a new form of low-power wireless sensing technology that could soon let users “train” their smartphones to recognize and respond to specific hand gestures near the phone. The “SideSwipe” technology uses the phone’s wireless transmissions to sense nearby gestures, so it works when a device is out of sight in a pocket or bag and could easily be built into future smartphones and tablets.

Reliability Testing of GORE® Protective Vents in LED Luminaires

Outdoor lighting systems are designed with sealed housings to protect against environmental contaminants. Atmospheric conditions such as temperature shifts and relative humidity present challenges to the reliability of outdoor luminaires. Changes in ambient temperatures can lead to significant pressure differentials. Over time, pressure on the enclosure seals can cause them to fail and allow contamination and/or water to breach the enclosure. This shortens the life of the luminaire by damaging the wiring, leads and other electronics of the power supply driver and the LEDs. The moisture also reduces light efficiency and can cause condensation to form on the lenses and reflectors.

Fourier Transform Spectrometer on Autonomous Self-Healing Hardware Platform

This liquid crystal waveguide-based platform provides self-healing for electronics in dangerous or hard-to-reach locations. NASA’s Jet Propulsion Laboratory, Pasadena, California The autonomous self-healing (eDNA) hardware platform is a reconfigurable field-programmable gate-array (FPGA)-type platform developed by Technical University of Denmark (patent: WO/2010/060923). It is capable of autonomously reconfiguring itself in case a fault is detected and, thusly, restoring functionality at a fault-free location on the chip.
